Buffer Overflow Vulnerability in VLC Player

VideoLAN recently published a security advisory warning of a buffer overflow vulnerability in versions 2.0.5 and earlier of VLC Media Player, which might be exploited to execute arbitrary code. This vulnerability was reported by Debasish Mandal , a vulnerabilty researcher



   The vulnerability is caused due to an error in the “DemuxPacket()” function (modules/demux/asf/asf.c) when processing ASF files and can be exploited to cause a buffer overflow via a specially crafted ASF file. To exploit the vulnerability, a user must explicitly open a specially crafted ASF movie. 

Successful exploitation may allow execution of arbitrary code, but requires tricking a user into opening a malicious file. 

VideoLAN advises users to refrain from opening files from untrusted locations and to disable the VLC browser plug-ins until the issue is patched. A patch will be included in VLC 2.0.6, the next version of the media player, which is only available for testing purposes at the moment.
